HAND-olLER.

SPECIFICATION forming part of Letters Patent No. 274,683, dated March27, 1883.

Application led November 1], 1882. (No model.)

T o alt whom it may concern:

Be it known that we, CHARLES WELDY and GEORGE WITMAN, citizens of YtheUnited States, residing at thecity of Beading, county of Berks, andStateof Pennsylvania, have invented certain new and useful Improvements inHand-Oilers, of which thefollowing isa specification. i Our inventionrelates to improvements in hand-Oilers adapted to the use of engineers,machinists, and others; and the object is to supply a want for a simple,reliable, and cheap oiler. This we attain by' adding to the rod of theusual plunger-spout oiler a threaded reenforce of about one-half thelength of thev spiral spring used thereon, and upon which a milled-headnut freely works.

Referring to the drawings herewith, which form part of thisspecification, Figure l represents an exterior elevation of our improvedoiler. Fig. 2 represents a sectional elevation, showing the interiorVarrangement. Fig. 3 is y a plan showing in dotted lines the guide forvthe rod; Fig. 4, detailof plunger-rod This `cross-piece is 'placed soas to :fall between the handle and the filling-tube A3.Immediatelyin'front ofthe handle A5 is soldered upon the cone A aperforated guide-piece, A", through which the plungergrod is led out ofthe can.

D is the plunger-rod., having at its upper end a leather piston, F, tting the interior of the spout at the intersection of B2 with the same.Midway between the plunger F and the cross-bar G a threaded re-enforce,D', is soldered to the rod, having a milled nut, E, working freely onthe same. The rod after passing through the cross-bar is bent twice at'rightangles toward the piston F, the distance between the bendscorresponding with the distance between the centers of the can andguidepiece A4. A spiral spring, g, occupies the space between thecross-piece C and the milled nut E, while the short protrude'd end isprotected by a thumb cap piece, H.

We do not confine ourselves to the form 4of can shown, as theimprovement may be applied to any of the usual oiler. nozzle-cans.

In constructing the cans the cross-piece G is soldered or secured inplace in the interior of the cone or top, and the guidepiece A4 upon theexterior of the cone or top. Thebent plunger-rod is passed through thecross-piece and its terminaljbend through the guide-piece. rEhere-enforce D is then secured upon the rod at the proper place, and thespiral spring q` is placed over the rod uponthe cross-bar C and themilled nut screwed down upon the Vsame', which secures it in place,andthe extreme end is crowned with the plunger F, of leather or elasticmaterial. The cone or top Ais now soldered or secured to the body A..The length of the rod D is so adjusted that the plunger F shall lie inclose proximity with the junction of B and B2.

The voperation of the oileris as follows: The can is filled through thefilling-tube A3. Then faking the can by the handle A5, with one fin-`ger resting upon the cap H, the spout is placed over the hole or placeto be oiled and the cap pressed down. This compresses the spring g andwithdraws the plunger F away from its seat into a wider portion of thetaper spout, and the oil or lubricating material passes around the sameand out of the end of spout B2. moment the pressure 4on the cap isrelieved the spring expands and the dow of oil is cut off. Sufficientair passes the rod D into the can throughthe guide-piece A1 to balancethe column and permit a steady flow of oil as long as the cap Hispressed down. Should the spring become weak, the spout is unscrewed andthe milled nut screwed farther down upon the reenforce, and in case offailure of spring anew one may be placed in position, winding it overthe rod until it surrounds the salme.

In all the oilers of which we have knowledge, where the spout was closedby an automatic piston, plunger, or valve, the springs would in timeclog and become. inoperative, and there being no provision for repairsor' renewal the cans were thrown away. By our improvement the life ofthecan is extended, and the cer- The 2. In an oiler, as described, acentrally-per"- forated cross-bar, O, in combination with the 15 oiler AA', plunger-rod D, springg, 11e-enforce and nut D E, and guide-piece A,substantially as and .for the'purpcsey specified.
